How currency inflation affects monthly salary in your country?

Affects everything.

Negatively. It destroys the purchasing power.

This specific issue effects me as a freelance voiceover artist and creative professional. I work with dozens of companies on a yearly basis and each company is located in a different part of the world. Since this is pretty much the future of business... this idea of a borderless business paradigm it is important to:

a. have a number of available payment methods that your clients can pay you with.

b. be aware of the currency fluctuation that occurs.

c. be aware of the different banking charges that you can get charged through bank transfers or paypal fees or western union fees.

For some countries I stick to a specific currency when I charge a client. For example, for my Canadian / Egyptian and Jordanian clients I charge them in the local currencies and do not charge them an extra banking fee because I already have bank accounts in these3 countries. So I just ask them to deposit the money in those accounts.

For countries like the UK I quote in GBP but invoice in USD... that is mainly because Paypal will charge me a huge amount of money if I recieve payment in GBP... it will try to automatically convert it to USD charging me at an inflated rate and making more money off that transfer than I deem fair.

For European countries I charge in Euro if they will be making a bank transfer but if its a paypal payment I invoice in USD.

Being aware of the fluctuations in currency rates is important but it isn't something you can really control. Being aware of banking charges on the other hand can help minimize financial drain on your freelance business (if you have one).

By the inflation the purchasing power will decrease and this will affect the living conditions for the Labor force and they will ask for more real wage since the prices are increasing and we 'll keep like this way until reach the long  equilibruim real wage .
